SCHNEIDER 140DDI35310 Discrete Input Module – Modicon Quantum Series
Imagine a high-speed bottling line, an offshore oil platform control room, or a municipal water treatment facility — all relying on split-second signal acquisition from hundreds of field sensors. When a discrete input module fails or goes missing, the entire PLC scan cycle loses its eyes. Operators fly blind. Production halts. Safety interlocks go unmonitored. The SCHNEIDER 140DDI35310 is the component that stands between controlled operation and unplanned downtime — a mission-critical interface between the physical world and your Modicon Quantum control system.
The 140DDI35310 is a 32-channel, 24 VDC discrete input module purpose-built for the Schneider Electric Modicon Quantum platform — one of the most widely deployed large-scale PLC architectures in global process and discrete manufacturing. Within the Quantum I/O family, the 140DDI35310 occupies the high-density, cost-efficient tier: delivering maximum channel count per slot while maintaining full IEC 61131-2 Type 1/Type 3 input compliance. It is found in tens of thousands of installations across petrochemical, power generation, automotive, and infrastructure projects worldwide.
